Illinois Central GP10 8256 was a 1970 Paducah Shops rebuild from an EMD GP9, on the number of which my sources are not in agreement. In this transparency by David V. Leonard, 8256 rests in the yard at Bloomington, Illinois on June 12, 1974 after the merger of the Illinois Central and the Gulf, Mobile & Ohio into the Illinois Central Gulf. It was sold to MidSouth Rail which renumbered it to 1059, but no additional information has turned up.
